JOSHUA BRIGGS, OF PETERBOROUGH, NEW HAMPSHIRE.

IMPROVEMENT IN OTTOMAN PIANO-STOOLS.

Specification forming part of Letters Patent No. 94,388, dated August31, 1869.

To all whom it may concern:

Be it known that I, JOSHUA BRIGGS, of Peterborough, in the county ofHillsborough and State of New Hampshire, have invented an ImprovedOttoman Stool for Piano-Fortes; and I do hereby declare that thefollowing, taken in connection with the drawings which accompany andform part of this specification, is a description of my inventionsufficient to enable those skilled in the art to practice it.

The invention relates to that class ot' pianoforte stools known asottoman stools,77 each having a square or oblong upholstered seat andseat-frame, supported upon four suitable legs.

My improvement has reference to provision i for slight adjustment of theseatl as to height,

the improvement consisting, primarily, in combining with a hinged seatmeans for raising the seat at one edge thereof.

The drawing represents a cross-section oi' a stool embodying myimprovement.

c denotes the upholstered seat, supported upon a base or frame, b, whichis mounted upon the tops of iour legs, two of which, c o, are shown inthe drawing. The seat is hinged on one side to the frame b, as seen atd, and the frame b is made in box form, as seen at e, the seat formingthe hinged cover to the box.

0n one side of' the box I make a step or oset, f, and over this I hingeto the bottom board g ot' the seat a swing prop or leaf', h, as seen inthe drawing. When this prop is swung up toward the seat, the seat shutsdown upon the frame, and occupies a horizon- If still further to beelevated, the seat is raised until the prop may rest upon the step f,

bottom of the seat-board, as seen at m.

and it may be still further elevated by supporting the prop upon the top'i and against the iiange 7c. lt will seldom be necessary, bowever, toraise the seat to this extent, but its capability of slight adjustmentas to height is a very desirable feature in a stool of this class.

To enable the seat-board to come slightly down below the top of theframe b, (to impart a finish to the edge,) and to conceal the hinges, Ichamfer oft' the top ofthe wall lof the frame b, and fasten one part ofeach hinge upon this beveled surface, setting the other part into theBefore screwing down the lower leaf of the hinge, the rep orseat-covering cloth is drawn under the leaf, thereby concealing thehinge-the seat, when down upon the frame, showing no a seat which may bevaried in height at the will of a performer.

I do not claim, broadly, a chair or stool whose seat is hinged, so as tobe elevated at one side 5 but I claim- In an ottoman stool forpiano-fortes, whose seat is adjustable in height, setting the hingesupon the inclined top edge of the frame b, concealing them by drawingunder them the top covering-cloth, and sinking the seat bef neath thesurface of the frame, substantially as set forth.

JOSHUA BRIGGS.
